Description
ST-GS220 is a high-efficient and high-reliable ground loop isolator for video signal over coaxial cable, which needn’t power. Features strong lighting-proof function, which can effectively solve the interference caused by different ground potential during the transmission of the signal. Besides, it can also be exempt from being damaged by reaction and operation of the over-voltage and the discharging of the static electricity, restore the standard video signal, pick up clear video picture, effectively eliminate the split, interference and scrolling of the picture. It is widely used in various complicated system in security surveillance.
 
Features
· Power requirement: No power required, easy installation;
· Functions: Minimize the common-mode interference and high frequency interference of the signal distortion caused by ground loop video, effectively eliminate the split, interference and scrolling of the picture.
· Isolation Voltage: 800V;
· Safety: interference minimizing、efficient lightling-proof、free from static electricity、transient surge protection for line;
· Design; ABS plastic injection-wide,waterproof, compact ;
· Installation: Double-end cable, no extra connection cables, easy to installation.

Installation steps
 
Please install as the following step
1.Make sure whether the device installation follows the manufacturers instructions
2.Check whether each terminal of the BNC is in good connection
3.Check whether the actual distance is more than the maximum transmission range of the device
4.Check whether the quality of the transmission cable is reliable
5.Replace the equipment that does not work with a video signal ground loop isolator confirmed to work
6.If you still can not screen out the fault, please contact the manufacturer
